PRIORITY OF INVENTION

This application claims priority from U.S. Provisional Application No. 62/248,196, filed 29 Oct. 2015, which is hereby incorporated by reference in its entirety.

BACKGROUND

As a method of birth control, condoms have many advantages of low-cost, easy to use, and providing protection against numerous sexually transmitted infections (STIs). However, the drawbacks to more universal and consistent use of condoms are their tendencies to decrease pleasure and/or induce the loss of erection. The reason for these obstacles is that condoms are made from hydrophobic materials, such as latex, polyurethane, and polyisoprene. These hydrophobic materials are excluded from the human physiological environment, such as the surface of the skin. Thus, currently used condoms always cause the foreign body sensation to decrease pleasure and/or induce the loss of erection.

In addition, condoms are currently most often made from natural latex, which is derived from the sap of some plants. However, the use of latex condoms may cause allergic symptoms in people with an allergy to latex. In some normal people, the development of a latex allergy may be caused by the repeated use of latex condoms. To reduce the level of the allergy, some chemical synthesized materials, such as polyurethane and polyisoprene are used to make male condoms. A female condom was also developed, which is often made from nitrile. The condom made of natural latex has high quality of elastic properties. It can be stretched in excess of 800% before breaking and the tensile strength exceeds 30 MPa. A polyurethane condom has several better properties than latex condom: it does not have an odor; has a higher efficiency to transmit body heat; is less allergenic; has a longer storage life, and can be used with oil-based lubricants. However, a polyurethane condom has less elasticity than a latex condom. It is more likely to lose their shape, bunch up, break or slip than latex. Similar to a polyurethane condom, a nitrile condom has improved chemical resistance. However, it is less elastic than a latex condom too. A polyisoprene condom has less tensile strength than latex condom. However, it has the highest elongation before breaking (>1050%) and lower moduli, which result in increased softness. It also does not have an odor and has a higher efficiency to transmit body heat. In addition, it does not include proteins that cause latex allergies.

To benefit the erection, several patents have described condoms coated with active ingredients on their surface. For example, U.S. Pat. No. 4,829,991 describes a condom that coated with a vasodilator in its interior surface except at the closed and open end portions. The vasodilator (such as a nitroglycerine) transdermal coating on the surface of the condom contacts the skin of part of the shaft of the penis, after it is fitted onto a penis. The friction between the condom and the penis breaks the surface tension of the transdermal vasodilator coating and results in the gradual development of an erection.

U.S. Pat. No. 6,840,244 also describes a condom that can be used to deliver erectogenic compounds. In this patent, an erectogenic compound is coated on the interior surface of a condom in the closed end. The erectogenic compound is applied as a finely-divided form or as a film layer by the use of a solvent carrier, which is subsequently evaporated to leave the compound immobilised. In another way, the erectogenic compound is applied on the condom as a component of a composition, which is dispersed or dissolved in a gel carrier including a liquid medium and a thickening agent. The liquid medium is vegetable oil or a polyhydroxy-based medium. And the thickening agents include hectorite, jojoba oils, waxes or cellulose derivatives.

Int.'l Pat. Publication WO/2009/134767 describes a condom that affixes a low melt wax bead comprising an active ingredient on the interior surface of the condom in its tip. The bead comprises a polyethylene glycol-based wax or a natural wax mixed with polyethylene glycol. The wax softens in the range of 25-40° C. to substantially expose the active ingredients. Active ingredients include spermicides (e.g. nonoxynol-9), vasodilators (e.g. nitroglycerin, niacin, and sildenafil citrate) and male desensitizing agents (e.g. benzocaine). The exterior surface of the condom is free of the active ingredient.

It is an easily manipulated method to coat active ingredients on the surface of a condom described as above patents. However, the coating materials such as polyethylene glycol, jojoba oils, waxes or cellulose are very sticky, which are not pleasurable to users. In addition, these smooth adjuvant materials make condoms easily slipping off.

Recently, Int.'l Pat. Publication WO/2015/068174 describes a condom made of polymers mixed with graphene and its derivatives. The graphene and its derivatives are loaded with or without active ingredients to uniformly disperse into polymers. The mixed polymer is used to prepare condoms by dip casting methods. The pharmaceutical active ingredients in the nanocomposites of graphene and its derivatives are prepared for release during intercourse to increase the sexual pleasure. The condom prepared in this patent has higher mechanical strength and heat transfer. However, the active ingredients are trapped in the nanoparticles of graphene and its derivatives. Thus, the release rate and efficiency of the active ingredients are limit. In addition, the outer surface of the graphene nanoparticle is hydrophobic, which is not observably change the polarity of the surface of condom.

DETAILED DESCRIPTION

A skin-like condom containing pharmaceutical active ingredients that uniformly distribute on the surface of latex particles is described herein. The term condom and skin-like condom includes a condom, patch, or glove.

Condoms are prepared using polyisoprene latex containing prodrugs of nitric oxide. The prodrugs of nitric oxide will be released from these condoms; transported into smooth muscle cells; decomposed to nitric oxide. The nitric oxide activates the erection and female arousal.

A condom assembly is described herein, including at least one of a condom, patch or glove used to deliver other active ingredients selected from the group consisting of arginine, vasodilators or related compounds, including the nitrates, ergot alkaloids, long and short acting alpha-adrenoceptor blockers, anti-hypertenives, the prostaglandins or phosphodiesterase inhibitors. The above active agents may be used either alone or in combination.

In one or more options, the condom, patch or glove may include or not include a hydrophilic adjuvant, such as lecithin and its analogues, polysaccharide analogues, or proteins.

In one or more embodiments, a condom, patch or glove is made of natural latex, synthetic latex or the mixture of natural latex and synthetic latex containing extra protein(s).

In one or more embodiments, a condom, patch or glove is made of natural latex or synthetic latex containing protein(s) and phospholipid(s).

In one or more embodiments, a condom, patch or glove is made of natural latex or synthetic latex containing protein(s) and polysaccharide.

In one or more embodiments, a condom, patch or glove is made of natural latex or synthetic latex containing protein(s), phospholipid(s), and polysaccharide(s).

In one or more embodiments, synthetic latexes include polyurethane, polyisoprene and nitrile latex.

In one or more embodiments, proteins are derivable from caseinate (Na, K, NH₄, Mg, Ca, Zn), extraction of milk, soybeans, peanuts, corn and other natural objects.

In one or more embodiments, phospholipids include lecithin, phosphatidic acid, phosphatidylethanolamine, phosphatidylserine, phosphatidylinositol, phosphatidylinositol phosphate, ceramide phosphorylcholine, ceramide phosphorylethanolamine, or ceramide phosphoryllipid.

In one or more embodiments, polysaccharides include starch, glycogen, cellulose, chitin, callose, laminarin, chrysolaminarin, xylan, arabinoxylan, mannan, fucoidan or galactomannan.

The active ingredient has higher hydrophilic property than latex particle. Thus the novel condom containing pharmaceutical active ingredients on the surface of latex particles has increased polarity and electroconductivity. The condom itself provides increased pleasure to users since its surface is friendly to human skin. The active ingredient releases out promptly and continuously, which provide constant enhancement for the erection of penis. Some active ingredients (e.g. nitric oxide derivatives) can also increase female arousal, which provide increased pleasure for both partners. In addition, the active ingredient(s) can increase the mechanical strength and heat transfer ability of the condom. The novel condoms containing pharmaceutical active ingredients on the surface of latex particles are prepared to enhance a male erection and a female arousal, increase pleasure for both partners, prevent pregnancy and sexually transmitted diseases.

The present invention also provides a novel prodrug of nitric oxide, D-glucosylated PROLI/NO (1, FIG. 1). This prodrug and its derivatives may arouse and enhance the erection for male, and may also arouse and enhance sexual excitement for female.

The disadvantage of currently used condoms is the decreasing pleasure and/or inducing the loss of erection, since they were made of hydrophobic materials that are excluded from the human physiological environment, such as the surface of the skin. In this invention a pharmaceutical active ingredient is uniformly distribute on the surface of latex particles to increase the polarity and the mechanical strength of condom, which is friendly to human skin to increase pleasure for both partners. In addition, the active ingredient releases out from the condom, provides enhancement for the erection of penis and female arousal, results in more pleasure to both partners.

One embodiment provides a condom (FIG. 2I) made of polyisoprene latex composition comprising D-glucosylated PROLI/NO (1), which is a prodrug of nitric oxide. The formulation (A) of this polyisoprene latex contains 1.0 phr of D-glucosylated PROLI/NO and small amount of hydrophilic adjuvant. As a control, another formulation (B) just contains polyisoprene latex without D-glucosylated PROLI/NO and hydrophilic adjuvant. The condom made from formulation A has a much higher hydrophily and litter higher mechanical strength than that of formulation B. The contact angle (θ) of 5 μL water on the surface of polyisoprene condom made from formulation A is 18 degrees, and the elongation is 1400%. Comparatively, the contact angle (θ) of 5 μL water on the surface of polyisoprene condom made from formulation B is 82 degrees, and its elongation is 1050%.

The second embodiment provides a condom (FIG. 2II) making up of formulation (A) of latex on the internal side and formulation (B) on the external side of condom. The third embodiment provides a condom (FIG. 2III) making up of formulation (A) of latex on the external side and formulation (B) on the internal side of condom.

Then smooth glass formers are dipped in the formulation (A) of latex suspension for 1 min and dried at 60° C. for 5 min. This procedure is repeated one time. Then the formers coated with the formulation (A) of latex are dipped in the formulation (B) of latex suspension for 1 min and dried at 60° C. for 5 min. The latter dipping and drying procedures are repeated one time. Finally, the condoms are cured at 130° C. for 15 min.

Example 4

The smooth glass formers are dipped in the formulation (B) of latex suspension for 1 min and dried at 60° C. for 5 min. This procedure is repeated one time. Then the formers coated with the formulation (B) of latex are dipped in the formulation (A) of latex suspension for 1 min and dried at 60° C. for 5 min. The latter dipping and drying procedures are repeated one time. Finally, the condoms are cured at 130° C. for 15 min.

Example 5

The smooth glass formers are dipped in the formulation (A) of latex suspension for 1 min and dried at 60° C. for 5 min. Then the formers coated with the formulation (A) of latex are dipped in the formulation (B) of latex suspension for 1 min and dried at 60° C. for 5 min. The latter dipping and drying procedures are repeated one time. Then the formers are dipped again in the formulation (A) of latex suspension for 1 min and dried at 60° C. for 5 min. Finally, the condoms are cured at 130° C. for 15 min.

Example 6

One condom containing 7 mg of D-glucosylated PROLI/NO is suspended in 20 mL of pure water. A 100-μL of sample is taken out at 2 min, 5 min, 10 min, 15 min, 20 min, 25 min and 30 min. The UV absorption is measured at 255 nm. As a control, a condom without the D-glucosylated PROLI/NO is also treated as the same way. The release amount is calculated based on the UV absorption of pure D-glucosylated PROLI/NO.

Example 7

In one or more embodiments, a skin-like condom is described herein, which mimics the membrane of living cells to increase pleasure. The human cell membrane is a biological membrane that surrounds the cytoplasm of living cells. It involves in a variety of cellular processes such as ion conductivity, cell adhesion and cell communication. Cell membrane consists of a lipid bilayer with embedded proteins. The glycosylation of the surface of embedded proteins increase the hydrophily of the membrane. In this study, we added a D-glucosylated PROLI/NO and several hydrophilic adjuvants into

-   the polyisoprene latex and used this mixture to prepare condoms. The     hydrophilic compounds located at the surface -   of the polyisoprene condom to mimic the surface of cell membrane for     higher hydrophily and increased sensation.

Condoms have been prepared with two different formulations of polyisoprene latex (FIG. 4). Both polyisoprene latex formulations contain Cariflex IR0401 latex (Kraton Polymers U.S LLC); bridging agent (sulfur); activator (ZnO); accelerators (ZDEC and DPG); and anti-oxidant (BHT). Besides these uniform agents, formulation A contains D-glucosylated PROLI/NO, sodium caseinate, lecithin and sodium carboxymethyl cellulose; formulation B only contains a sodium caseinate.

The contact angle (θ) of 5 82 L water on the surface of polyisoprene condom made from formulation A is 18 degrees (FIG. 5), and the elongation is 1400%. The active ingredients in latex dramatically increases the hydrophily and slightly increases the flexibility of the condom. The contact angle (θ) of 5 μL water on the surface of polyisoprene condom made from formulation B is 82 degrees, and the elongation is 1050%.

In summary, we prepared skin-like condoms using two formulations of polyisoprene latex to mimic the membrane of living cells. These condoms have increased hydrophily and flexibility compared to condoms that made from natural latex. The condoms prepared in this study will increase pleasure and decrease the rate of latex allergies.

The present invention provides a novel condom containing pharmaceutical active ingredients that uniformly distribute on the surface of latex particles. The active ingredient has higher hydrophilic property than latex particle. Thus the novel condom containing pharmaceutical active ingredients on the surface of latex particles has increased polarity and electroconductivity. The condom itself provides increased pleasure to users since its surface is friendly to human skin. The active ingredient releases out promptly and continuously, which provide constant enhancement for the erection of penis. Some active ingredients (e.g. nitric oxide derivatives) can also increase female arousal, which provide increased pleasure for both partners. In addition, the active ingredient(s) can increase the mechanical strength and heat transfer ability of the condom. The novel condoms containing pharmaceutical active ingredients on the surface of latex particles are prepared to enhance a male erection and, a female arousal, increase pleasure for both partners, prevent pregnancy and sexually transmitted diseases. The present invention also provides a novel prodrug of nitric oxide, D-glucosylated PROLI/NO. This prodrug and its derivatives may arouse and enhance the erection for male, and may also arouse and enhance sexual excitement for female.
